Snapshots failing repeatedly on beta3

Kopia UI v0.8.0-beta3 windows, I am saving to an sftp server on a nas. It was working fine until 5 days ago (I think it is the day it upgraded to beta3. I also updated windows from 1909 to 20H2 in the same ballpack). Thanks for your help!

Apologies, it fixed itself after a reboot (I have been using hibernation in the last week).
Not sure what this was about, will report back if funny business happens again.

Actually it broke again. Something weird is happening after resuming from sleep:
